Summit RacingSummit Racing Verified Purchase

Thes headers fit the heads well.the number #8 cylinder header tube doesnt have any clearance for th plug boot not to hit and melt. I also had an issue with the converter pipe lining up correctly with header flange. I had to cut and weld my flang. I called summit with this concern and they were more than willing to help i am very pleased with the service i recieved but the product not so much. ...read more

Summit Racing® Truck Headers SUM-G9048

Summit RacingSummit Racing Verified Purchase

I installed these on a 2001 4x4 Silverado and the fit was excellant. #8 spark plug is a little close to headers but manageable. The stock exhaust matched up perfectly and had them on in a couple hours. Shipping was free and fast, ordered them on a Tuesday and was installing them on a Thursday.

good but needs to be looked at

Summit RacingSummit Racing Verified Purchase

These arrived in a pace setter box...are they pace setters? Who can say. What I can say is that there was a lot of weld that I had to grind off of the inside of the collector and especially the EGR tube. These are a great bargain and seem to work pretty well, but you made need to do some grinding to get them there, check the internal welds. The inlet of the EGR tube was about 1/2 blocked with a big glob of metal. It took me about 20 minutes with my dremmel, but it's nice and smooth now. ...read more

Pace setter headers!!

Summit RacingSummit Racing Verified Purchase

Headers are awesome. The people I had install them. Not so much. Came back with a misfire code. My egr tube had a hole in it. And everything was filthy. In other words don't take you vehicle to mufflers and more.
